Wisconsin property tax appeals, 2027

In Wisconsin, you appeal a property assessment to the Municipal Board of Review, and the deadline is 48 hours before the Board of Review's first meeting, usually in spring, for the notice of intent to object. Each county below lists its own date, how to file and who hears the appeal. Sale prices are public record here, so recent sales of similar homes are the main evidence of market value.
